Context of Lesson:
The purpose of this lesson is for students to be able to discuss and investigate photosynthesis and respiration; what their formulas are and what the steps of the processes include. We get our food from plants and animals and this lesson can help students make the connection between the sun and how it interacts and affects living organisms (plants-->humans).
Opportunities to Learn:

Objectives: Compare the similarities and differences of photosynthesis and cell respiration.
List the components of the photosynthesis and cell respiration processes.
Diagram where the different products enter and leave the different processes.
Instruction:
Opening: Have a class discussion with the the class about what they know about plants and how they get energy. Are the processes similar to humans? What are some things a plant needs? I will have some plants available to look at in the front of the room if the students would want to observe the structure of the plant which could give them some clues as to how the plants get energy and how they give energy off too. After hearing what the students have to say about photosynthesis and writing some of their ideas on an overhead in a column, I will have them fill out a KWL chart in pairs at their assigned tables.I will have students share with the class some things that they had written in the 'what i want to learn' column. This will help me figure out what they know, what they need to know and what they are curious about. I will tell them after they have completed the KWL chart that it will be revisited at the end of the lesson to compare their knowledge know and their knowledge after the lesson.
Engagement: The students will work in pairs while I will guide them through an online Webquest about photosynthesis and cell respiration in the computer lab if available. This Webquest walks to students through the two processes step by step with pictures and animation. I will have my own computer that is hooked up to a large monitor for the class to see while we complete the Webquest together along with a discussion along the way. After completing the Webquest, the students will complete a worksheet that corresponds to the Webquest. After the students have finished the worksheet (in-class or homework depending on time). I will show a PowerPoint presentation on Cellular Respiration (what it is, how is it similar to photosynthesis, how it differs from photosynthesis...). Throughout the slide show I will be asking the students these questions as well as answering any questions or confusion they may have. Following this slide show, I will hand out a Venn diagram for the students and I to fill in. We will discuss the similarites and differences of photosynthesis and cellular respiration together. I will be filling in a Venn diagram on the overhead/board while the students fill theirs in.
Closure: I will have the students revisit their KWL charts from the beginning of the lesson and fill in the 'what I have learned' column. We will discuss as a class some similarities that the students have in their final column of their charts. As a closing, I will ask students if they still have any confusion about some of what happens in these processes and have them write it on an index card as an exit slip activity.
Assessment:
-KWL chart
-Webquest worksheet
-Quiz on the two processes (short answer, multiple choice, diagram)
